RAILROAD CROSSIN G.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed January 10, 1919, Serial No. 270,534. Renewed December 13, 1919. Serial 'No. 344,759.

To all whom it may concern Be it known that I. CHAnLEs A. ZOBEL, a citizen of the United States, residing at Roanoke, in the county of .Randolp'h and State of Alabama, have invented new and useful Improvements in Railroad-Crossings,

ofwhich the following is a specification.

This invention relates to new and useful improvements in railroad crossings and one object 'ofthe invention is to provide means for preventing the wheels of a train passing along one track contacting with the rails of the cross track.

Another object of the invention is'to place one track above the other and to provide bridging means for bridging the lower track when the train passes over the upper track.

."lnother object of the invention is to provide means for normally holding the bridging means in operative position and to provide means, operated by the train, for moving said bridging means into inoperative position by a train moving along the lower t 'ack.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

in describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the severai. views, and in which Figure 1 is a plan view of a crossing supplied with my invention.

Fig. 2 is a side elevation.

Fig. 3 is a section on line 33 of Fig.

F -l is a section on line 4-4. of Fig.

Fig. 5 is a section on line 5-5 of Fig. Fig. 6 is a section on line 6 6 of Fig.

Figs. 7 and 8 are detail views. J

As shown in these views the parallel tracks A and B have their rails slightly lower than the rails of the track C which is a cross track. I prefer to make the parallel tracks A and B continuous while the cross track 0 is formed in sections with the ends of the sections abutting the rails of the parallel tracks A and B. These abutting ends have the r pp p rtions, cut aw y as a l so that'the wheels of a train passing along either track A or-B will not contact with said abutting ends of the rails of track C. These sections of track C are secured to bed plates 2 by bolts or the like. The spaces formed by the cut away portions are bridged by the bridges 3 which are pivoted to the bed plates by means of the bolts 4. Each of these bolts has secured to it a spring 5 which tends to hold the bridges in operative position with their inclined ends 6 engaging the inclines '7 formed on the cut away ends of the abutting portions of the rails of track C.

As will be seen each bridge 3 is provided with a recess 3 at one end thereof on its under face for receiving the tread part of the rail of the parallel track. By this arrangement of parts when the bridges are closed the sections of the rails of track 0 are connected together so that said track is continuous and a train may pass over the same .without its wheels contacting with the rails of tracks A and B, thus doing away with all jolting and bumping.

As before stated the springs 5 normally hold the bridges in operation position and in order to throw said bridges into inoperative position to allow a train on track A or B to pass over the crossing, I provide means operated by the train on track A or B to actuate said switches. These means consist of a cranked rod 8 rotatably supported on the tracks A and B, one on each side of the crossing. These rods are provided with a crank at each end and a crank in the center. A second rod 9 is rotatably supported adjacent each of the cranked rods and each rod 9 is provided with an arm 11 and a central arm 10 adapted to engage with the middle crank of the rod 8. The arms 11 engage pressure bars 12 movably secured to the rails of the parallel tracks by means of the bolts 13 engaging slots formed in said pressure bars 12. As will be seen from Figs. 3 and 6, the arms 11 project upwardly at an incline and their upper ends engage the lower face of the short arms of the bars 12 which are of L- shape in cross section. As will be seen these pressure bars extend a considerable extent on each side of the crossing so that they will be in contact with the wheels of the t n a it p e o er the crossing. In

. The bridges are connected together by the short rods 15 so that the bridges of the rails will be moved in unison. The pressure bars 12 are held in their uppermost position by means of the springs 16 placed along the track and having their ends for holding the pressure bars in their highseated under the said pressure bars.

The rods are connected with the bridges by means of the studs 17 carried by ears 18 on said bridges.

'It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is I 1. A railroad crossing having one track in a higher plane than the other track, said higher track having cut away portions leaving spaces for receiving the lower track,

- pivoted bridges for said spaces having in- 'clined ends engaging the inclined ends of the rails of the higher track and each having a recess on its under face for receiv ing the tread of the rail of the lower track train on the lower track.

2. A railroad crossing having one track in a higher plane than the other and the rails of said higher track having portions cut away to form spaces to receive the rails of the lower track, pivoted bridges for said spaces, spring means for normally holding said bridges in operative position, rods connecting the bridges of each pair together, a cranked rod located on each side of the crossing, rods connecting said cranked rods with the bridges, pressure bars adapted to be engaged by the train on the lower track, means operated by said pressure bars for rocking the cranked rods and spring means est position.

3. A railroad crossing having one track in a higher plane than the other and the rails of th'e'higher track having cut away portions forming spaces for. receiving the rails ofthellower track, pivoted bridges for said spaces, spring means for normally holdingsaid bridges in operative position,

' a cranked rod on each side of the crossing, rods connecting the same with the bridges,

a second bar located adjacent each cranked bar, arms on said second rod, one of which engages a crank on said'cranked rod, pressure bars movably connected with the rails of the lower track and engaging the arms on said rod and spring means for holding said pressure bars in raised position.

In testimony whereof I aflix my signature.
